The reason bathrooms overrun is usually coordination, waiting for one trade before the next can start. We handle the sequence in-house with our own team, so the room progresses day to day. Waterproofing and falls are where bathrooms are won or lost. Tile backer or tanking in wet areas, correct falls in a shower, properly supported trays and sealed junctions are what stop water getting into the floor below. Who it's forHomeowners replacing a dated or leaking bathroom, landlords upgrading a rental, and anyone converting a bath to a walk-in shower or reconfiguring a cramped layout. When it's neededWhen tiles are cracked or grout is failing, when the room smells damp, when a leak has shown on the ceiling below, or when the layout simply does not work. Why a professional job mattersBathrooms are wet rooms with electricity in them. Waterproofing, falls, ventilation, correct waste runs and safe electrical zones all matter, and a leak inside a wall or under a tray is expensive and invisible until it is not. ## What Happens If It's Left Nothing outside a house gets cheaper to fix by waiting. Here is how this one escalates. ### A hidden leak damages more than the bathroom Water escaping under a tray or behind tiles soaks joists and the ceiling below. By the time it shows downstairs, the floor structure has been wet for a long time. ### Failed grout and silicone let water in Black, cracked or missing sealant at the bath, tray and splashbacks is a direct route for water into the wall. ### Poor ventilation breeds mould Moist air with nowhere to go condenses on cold surfaces, and mould takes hold in grout, sealant and the ceiling corner. ### Half-finished jobs stall Booking separate trades yourself means the room sits unusable while you wait for the next one to be free. ### Common mistakes we're called in to undo - Tiling straight onto plasterboard in a shower area with no tanking. - Fitting a tray or wet floor without correct falls to the waste. - Blocking or omitting extraction because the fan is noisy. - Choosing sanitaryware that does not fit the waste runs the room actually has. - Paying stage by stage on a day rate with no fixed overall price. ## Our Process The same five steps on every job, so you always know what happens next. 01 ### Site visit and layout We measure the room, check the existing plumbing, waste runs and ventilation, and work through the layout and what you want from the space. 02 ### Fixed price in writing A free, no-obligation quote covering strip-out, disposal, labour and the fit-out, with sanitaryware and tiles priced in or supplied by you. 03 ### Strip-out and first fix The old suite comes out and is taken away, walls and floors are prepared, and pipework and cabling are run for the new layout. 04 ### Waterproofing, tiling and fit-out Wet areas boarded and tanked, floors and walls tiled, then trays, baths, basins, WCs, screens, taps and showers fitted and tested. 05 ### Testing, sealing and completion Everything run and checked for leaks, silicone finished neatly, room decorated and cleaned, guarantee handed over. ## What You Get ### One team, one programme Strip-out, plumbing, tiling and finishing handled by the same firm, so there is no dead time between trades. ### Properly waterproofed Tanking and correct falls in wet areas keep water where it belongs. ### Fixed price before we start The figure you agree is the figure you pay, no day rates creeping through a two-week job. ### Tested before handover Every fitting run and checked for leaks before we call the job finished. ### Finished, not just fitted Tiling, sealing, making good and decoration completed so the room is ready to use. ### Guaranteed and insured 10-year workmanship guarantee, public liability and employer's liability cover. ## Bathroom Fitting in Detail Materials, methods and the variations we cover across Cardiff, Newport and the wider South Wales area. ### Full bathroom installations Complete strip-out and refit including bath, shower, basin, WC, furniture and storage, with disposal of the old suite and any rubble included. ### Shower rooms and bath-to-shower conversions Converting an unused bath into a walk-in shower, with tray or level-access forming, screens, and the waste and falls set out correctly for the new position. ### Waterproofing and substrates Tile backer board and tanking systems in wet zones, sealed at joints and penetrations, with floors checked for deflection before tiling so grout lines do not crack. ### Tiling Wall and floor tiling in ceramic, porcelain and large format, set out so cuts fall in the least visible places, with the correct adhesive and grout for the substrate and the wet environment. ### Plumbing, ventilation and layout changes Moving waste runs and supply pipework where the layout changes, and making sure extraction is adequate; the single biggest factor in whether a bathroom stays mould-free. ### En-suites, cloakrooms and rentals Small-room installations where every millimetre of the layout matters, and hard-wearing rental specifications built for turnover rather than showroom looks. ### Where we carry out this work We work from Crumlin Drive in St Mellons across Cardiff, Newport, St Mellons, Vale of Glamorgan, Caerphilly, Penarth and the surrounding South Wales area.

We measure on site and give you a free fixed written price. How long does a bathroom take?A typical full bathroom runs over one to two weeks depending on the tiling and any layout changes. The programme is set out in your quote before we start. Will I be without a bathroom the whole time?The room is out of use during the fit. Where the property has only one bathroom, we sequence the work to get the WC back in commission as early as possible. Can I supply my own suite and tiles?Yes. Plenty of customers do. Just have it on site before the start date, and we will check the fittings suit the room before the old suite comes out. Do you move the layout around?Yes, within what the waste runs and structure allow. We will tell you at the site visit what is straightforward and what is not. Do you handle the tiling too?Yes. Tiling, sealing and making good are part of the installation, not a separate trade you have to arrange. Is the work guaranteed?Our workmanship carries a 10-year guarantee and we are fully insured. Are your quotes really free?Yes. We come out, look at the job properly and put a fixed price in writing. There is no charge for the visit and no obligation to go ahead. Do you charge a day rate?No. Every job is quoted as a fixed price. The figure you agree is the figure you pay, whether the work runs quicker or slower than we expected. Is the work guaranteed and are you insured?All of our work carries a 10-year workmanship guarantee, and we hold both public liability and employer's liability insurance. Ask to see the documents before work starts and you will get them. Which areas do you cover?We are based on Crumlin Drive in St Mellons and work across Cardiff, Newport, the Vale of Glamorgan, Caerphilly, Penarth and the surrounding South Wales area. ## Related Services ### Kitchen Fitting Units scribed to walls that are never straight, worktops jointed tight, appliances in and running, and the tiling and making good done: one fixed price, one team, one finish date.

We fill, sand, treat, prime and size before a brush or a roll goes near the wall, so the room still looks right in five years.
